Adrian Tomas Garcia

Mechanical Engineer with knowledge of backend development in Python

Mechanical engineer and software developer. Writing the software mechanical engineers need.

Building Python systems that solve real physical engineering problems: mesh repair pipelines for AI-generated 3D geometry, custom FEM solvers, and ML models that catch anomalies in gas pressure-reduction line data before they become failures.

That foundation, built by hand from scratch before leaning on any AI assistance, is what now lets me develop faster without losing precision, and without shipping code that shouldn't exist.

WORK EXPERIENCE

Career path in mechanical engineering and backend development

I've worked in roles combining mechanical engineering knowledge with Python software development, bringing together the potential of software tools and automation applied to the physical world.

And now that I have a solid grasp of programming fundamentals, I have the confidence to understand and fix what Artificial Intelligence writes.

R&D & Lab Operations EngineerFicta3D P.S.A Kraków, Poland Jul 2026 — Present ENGLISH

Leading the fluid-dynamics design of a new resin 3D printer (FICTA O): from CAD modelling to prototype validation and technical documentation.

KEY PROJECTS

Built from scratch, validated by hand

Structural Frame Calculation Program with AI ImplementationBachelor's Thesis · University of Salamanca School of Engineering, Zamora Presented September 2025 Advisor: Manuel Domínguez Lorenzo

Built a custom Python/NumPy FEM solver for 3D steel frames from scratch, implementing the direct stiffness method — the same method used by ABAQUS and ANSYS — with a Eurocode 3 section resistance check.
Validated the solver against hand-calculated textbook cases across multiple load orientations, documenting and root-causing the one discrepancy found instead of glossing over it.
Explored LLM-assisted structural design generation (custom JSON prompting) as a rapid-prototyping layer on top of the solver. Stack: Python · NumPy · PyVista · PyQt6 · OpenAI.

End-to-end design of a portable CNC milling machine with LinuxCNC, covering mechanical design, electronics, and control-system integration, and incorporating noise-reduction solutions for use at mineral exhibitions. Prototype pending manufacture due to budget.

WHAT I CAN DO FOR YOU

Three patterns, each visible in two places

Picking up what's needed before anyone asks.

At MkZ, without being specifically hired to write Python, I taught myself to program with FreeCAD, cutting modelling time on large assemblies by around 30%. At ENAGÁS I took that same initiative to build a complete data pipeline, from noisy sensor ingestion to trained model, that could later be deployed across the gas network.

MkZ · ENAGÁS

Turning a physical problem into a software pipeline.

For my Bachelor's thesis, I combined the direct stiffness method with strength-of-materials theory to solve 3D structures from scratch, validating it against hand calculations. At Ficta3D, I apply the same instinct to mesh geometry: shrinking-ball and nearest-neighbor queries over arrays to find thin walls before a print fails.

Thesis · Ficta3D

Documenting the work so the next person can use it.

Co-authoring two technical books: one on AI and ML applied to business, another on 3D printing and FEM-based design validation. The same initiative shows up day to day: complete, organized technical documentation, even when there are discrepancies, instead of hiding them.
